    "abstract": "We propose an optical ring interferometer to observe environment-induced\nspatial decoherence of massive objects. The object is held in a harmonic trap\nand scatters light between degenerate modes of a ring cavity. The output signal\nof the interferometer permits to monitor the spatial width of the object\u0027s wave\nfunction. It shows oscillations that arise from coherences between energy\neigenstates and that reveal the difference between pure spatial decoherence and\nthat coinciding with energy transfer and heating. Our method is designed to\nwork with a wide variety of masses, ranging from the atomic scale to\nnano-fabricated structures. We give a thorough discussion of its experimental\nfeasibility.",
